In this work, a method which seeks to locate a radial-color mark attached to the object using the high sensitivity of the phase to determine the position spatial and angular with subpixel resolution due to movement of an object in a 2D scene is presented. The reference pattern is formed by a regular distribution with radially symmetrical of color-RGB fringes. The reconstruction of the absolute phase associated to the fringes allows the location the precise center of the mark and it findsdoi:10.7149/opa.51.1.49052 fatcat:2i22kc7vlrh7pml3rhfyrkligu
